I have driven the 2013 SRT Viper, and it is good. It is visceral, it is mean, and it is so fast it's almost disgusting. I can't even imagine how nasty a non-street legal, racing only version must be. That's exactly what this bad boy is: the Viper GT3-R.

Ladies and gentlemen, meet the next generation of Viper for GT Class racing. This car builds upon the Viper GTS-R that campaigned the American Le Mans Series and this weekend's 24 Hours of Le Mans, and it can be privately owned.

Got a spare $459,000 just lying around that you don't know what to do with? Why not get one of these beasts for your racing team? You get a single-seat Viper built for solely competition with a host of goodies including an aerodynamic package, a six-speed sequential transmission with paddle shifters, six-piston front brake calipers with four-piston rears, an upgraded clutch and an 8.3-liter V10 putting down 680 horsepower and 640 lb-ft of torque.

The car was built by SRT and Riley Technologies in Mooresville, North Carolina, who have constructed everything from Daytona prototypes to GT cars. You also get that lovely red, white and blue paint job. If that thing passes by, I'll stand up and salute.

Check out the full specs on SRT's website. Orders are now being taken for late 2013 delivery. God bless America.
